When enabled, battery saver will automatically turn off services that are known to quickly drain the battery. You can turn on battery saver manually, or set it to turn on automatically when the battery is low.

When using the device for prolonged periods of time, such as when you're talking on the phone, charging the battery or browsing the web, the device may become warm. In most cases, this condition is normal and therefore should not be interpreted as a problem with the device.

The device has a protection feature that if the device becomes too warm (due to use of GPS while charging, Bluetooth while charging, etc), the auto protection feature will be triggered and the charging process will be stopped. Once the device cools down, the device will then begin charging again.

The USB cable acts as a trickle charger so it will take longer than if you were using an AC charger. While the USB will work, it is recommended to use the AC charger, especially if the battery level reaches 10% or below.

The battery indicator at the top of the screen will give you a visual estimate of your remaining battery life. For a more specific reading:

1. Go to the Applications list and tap Settings. 2. Tap battery saver. 3. Your battery info is displayed at the bottom of the screen.

NOTE: The Estimated time remaining field is based on low to moderate usage. If you are doing activities such as playing video/audio, playing games or consistently using your device, your battery will drain faster.

Your battery can take up to 3 hours to fully charge using the AC charger. It will take much longer using the USB as that is the trickle charge function. When the battery is fully charged, LED located on the upper left of the device will be a solid green.
